Ok, call me stupid, but is there a difference
between a Original Production Cel and just a
production cel?

Also, some online stores have there cels numbered
differently. For instance, "A1 End, or B12" while
another store lists them like "0001, or 0021" (and
those are really cheap, compared to the B12 and A1
end) 
Whats the difference, if any?

Also, does the website animaxis.com sell real
cels, or reproduction cels? Because i was looking
forever for "now and then here and there" cels,
yet couldn't find any for sale anywhere. But there
site lists over 1700 cels from that series... (and
those are the ones lists in the 0001 format) 

If someone could give me any information it will
be really helpful. I just would like to buy a real
cel, not the fake ones. 

If there is a really good site out there for good
cels, gladly list them

Thank you..
